Here is a small warehouse with attached office and sliding doors. The footprint is 1 9/16 x 3 1/16 and is relatively easy to build, featuring butt joints. It has sliding doors on both sides. If you don’t like the colors you can paint as desired. There are parts templates to print so you can save measuring steps.
Choice of materials is up to you. It can be done in wood but sketches are based on styrene thicknesses. If you use another material adjust dimensions accordingly. I used .010 and .030 styrene, and .040 Evergreen #4526 corrugated metal siding. Window openings are sized for Rich’s(Rslaserkits) #3980 and #3981. Office door is from his #3988. You can also adjust openings for your own windows. Window material is easily cut from clear blister pack plastic. Paint parts before assembly, except where the edges glue to other parts.
The building directions and materials are in the sketches, and to make your build easier you can enlarge them to full size and print them out. Read directions in assembly sketches before cutting out parts as you may want to change some sizes or cut fewer, or additional, openings.
Included sketches are: Overview sketches, Parts templates, Assembly sketches, and PDF's.
To print the part templates actual size, use the PDF's. Select best printer quality, set PDF zoom to 100%, and page scaling to "none" or actual size. Check your printed page to see that 3" lines are exactly 3" long. Once you have template printed, you can cut with scissors (leave a 1/8" border) and arrange on your material for maximum sheet usage. Part templates for siding are a mirror image, when needed, so that you can cut walls with siding side down (easier to cut). Be sure siding grooves are oriented correctly. Use rubber cement or Krylon Easy Tack Repositionable Adhesive to glue paper templates to your material and then just cut on lines. No measuring ! Paper comes off easily.
Cut out parts carefully using a SERB and straight edge. It is important to follow assembly sketches IN SEQUENCE or some parts may not fit, especially for roof sections.
Follow assembly sketch directions.
Roofing material is up to you and Rich has some good choices. Unless you bevel the roof pieces there will be a 1/32” gap. Overlapping roofing material will cover these gaps.
